Dear all,
I am using electronic expansion valve on my 15 kW scroll machine and it was running perfectly fine. Recently there was a small leak and i corrected it. After topping up some gas to counter the leak, my system was never stable and the super heat hunts between 3 to 6 deg K compared to earlier fluctuation which is less than 1 K.
Some one advice me that i should entirely evacuate the system and the recharge it to original charge level.
Even after that, my superheat still hunts. What could be the problem?
In between, i also would like to know more on the electronic expansion valve, mainly on the operating principles of the valve. I have found some info on the internet but not much technical explanations. Any sort of information is very much appreciated. I am using Emerson EX 2 together with the accompanied controller
Please help.
Regards,
jaya
